SEARCH-LIGHT.

SPECIFICATION forming part of Letters Patent N 0. 762,215, dated June '7, 1904.

Application filed January 6, 1904.

To all whom it may concern:

Be it known that I, W'ILLIAM OLIVER IVER- BER, a citizen of the United States, and a resident of the city of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Search-Lights; and I hereby declare that the following is a clear, full, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which similar characters represent the corresponding parts in all the views.

This inventionrelates to a search-light, and has for its object a positive mechanism for traversing said light in azimuth, in connection with a make-and-break device, to cause the light to be traversed intermittently in either direction over any desired arc and automatically reversed at either end of said arc; also, a traversing mechanism by which the light may be traversed in any desired arc ofazimuth by a continuous motion and then automatically reversed at either end of said are and returned by an intermittent motion.

It consists in certain novel features of construction and arrangements of parts, which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter given.

Of the drawings, Figure 1 represents a central vertical section through a light embodying the features of this invention. Fig. 2 represents a sectional plan on line 2 2 on Fig. 1. Fig. 3 represents an inverted sectional plan of the fixed base-plate for said light, showing the operating mechanism contained therein and the wiring therefor.

Similar characters designate like parts throughout the several figures of the drawings.

In the drawings, 10 represents a fixed basering provided with a groove in the upper end thereof and in which are mounted a series of balls 11 on which is mounted a traversing-plate 12. On the traversing-plate 12 are secured the uprights 13, in the upper ends of which are trunnion-beds 14 for the trunnions 15 of the search-light 16 ofv any well-known construction.

The search-light 16 is connected by an arm Serial No. 137,861. (No model.)

36, the opposite end of which encircles an eccentric 37 on a shaft 38, operated bya wormgear 39, a worm 40, and an actuating-motor 41 therefor. The base-ring 10 is provided with an annular gear 42, with which the gear 43 meshes. The gear 43 is secured to a shaft 44, on one end of which is a worm-gear 45, meshing with a worm 46, actuated by a motor 47 The motor 47 is connected by the wire 48 to a reversing mechanism 49 in the main circuit. In the main circuit is also a switch 50, by the operation of which a make-andbreak device 51 may be put in or cut out of said main circuit in order to cause the traversing of said light to be intermittent or continuous, as may be desired. The make-andbreak device 51 is operated by a worm 52, controlled by a motor'53. The base-ring 10 is provided with a groove 54, in which are adj ustably mounted stops 55, which may be clamped to said base-ring by means of the handle 56 in any desired position to limit the horizontal movement of the search-light in any predetermined arc. The stops have upwardly-projecting arms in the path of the lever 57 of the reversing mechanism 49, which may be of any well known construction. hen the lever 57 comes in contact with one of the stops 55, it will be moved to reverse the traversing mechanism and remain in its new position until it comes in contact with the other stop, when it will again be moved to change the traversing of the light to its former direction. This traversing may be done continuously or intermittently, according to the position of the switch 50.

It is believed that the operation of this invention will be thoroughly understood without any further description.

Having thus described my invention, I claim 1. In a search-light, a horizontal base therefor, a base-ring, a positively-moving motor to move said base about said base-ring, a makeand-break mechanism controlling said motor, and an actuator for said make-and-break mechanism.

2. In a search-light, ahorizontal base-plate therefor, a base-ring-for said base-plate, a positively-moving electric motor connected to said base-plate, a make-and-break mechanism controlling said motor, and a second motor for actuating said make-and-break mechanism.

3. In a search-light mounted to rotate in a horizontal plane, means for rotating said light intermittently over a predetermined are.

4. In a search-light mounted to rotate in a horizontal plane, means for rotating said light intermittently, and stops to limit the movement of said light.

5. In a search-light mounted to rotate in a horizontal plane, means for rotating said light intermittently, and adjustable stops to limit its movement.

6. In a search-light, a horizontal base-plate therefor, a base-ring for said base-plate, a positively-moving electric motor connected to said base-plate, a make-and-break mechanism controlling said motor, a second motor for actuating said make-and-break mechanism and a switch disengaging the make-and-brcak mechanism from the positively-moving motor.

7. In a search-light mounted to rotate in a horizontal plane, a make-and-break mechanism rotating said light intermittently, a reversing-switch, reversing the direction of said rotation and stops to actuate said reversingswitch. I

8. In a search-light mounted to rotate in a horizontal plane, a make-and-break mechanism rotating said light intermittently, a reversing-switch, reversing the direction of said rotation and stops to actuate said reversingswitch and limit the movement of the light.

9. In a search-light mounted to rotate in a horizontal plane, a make-and-break mechanism rotating said light intermittently, a reversing-switch, reversing the direction of said rotation and adjustable stops to actuate said reversing-switch and limit the movement of the light.

10. In a search-light mounted to rotate in a horizontal plane, a positively-moving motor, operatively connected to rotate said searchlight, a make-and-break mechanism, operatively connected to control said motor, a switch throwing said make and break control oif from said motor and an automatic switch for reversing the direction of rotation of said motor.

11. A search-light mounted to rotate in a horizontal plane, a positively-moving motor, operatively connected to rotate said searchlight, a make-and-break mechanism, operatively connected to control said motor, a switch throwing said make and break control of? from said motor and an automatic switch for reversing the direction of rotation of said motor, and adjustable stops actuating said automatic switch.

12. In a search-light mounted to rotate in a horizontal plane, means for rotating said light intermittently in one direction, and means for rotating said light continuously in the other direction.

13. In a search-light mounted to rotate in a horizontal plane, means for rotating said light intermittently in one direction, means for rotating said light continuously in the other direction, and stops to limit its movement.

1 1. In a search-light mounted to rotate in a horizontal plane, means for rotating said light intermittently in one direction, means for rotating said light continuously in the other direction, and adjustable stops to limit its movement.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
